To use nonstandard email domains, other than the nonstandard .local domain, you must edit the Authentication Manager ims.properties file on the web tier.
Before you begin
Where webtier-install-location is the installation directory.
Where nonstandard is the name of the nonstandard domain. For example, to support a .sms and a .local email domain, you would enter validDomainList=.sms;.local;
You can add more than one nonstandard domain. Separate each name with a semicolon.
The nonstandard domains are listed in /webtier-install-location/utils/resources/ims.properties.
